Datasheet  
AC/DC Convertor IC  
Non-isolated Type PWM DC/DC Converter IC  
Built-in Switching MOSFET  
BM2Pxx1W-Z Series  
General Description  
Key Specifications  
The PWM type DC/DC converter for AC/DC provides  
an optimum system for all products that include an  
electrical outlet. It enables simpler design of a high  
effective converter specializing in non-isolation.  
By a built-in startup circuit that tolerates 650 V, this IC  
contributes to low power consumption. A current  
detection resistor as internal device realizes the small  
power supply designs. Since a current mode control is  
utilized, the current can be restricted in each cycle and  
an excellent performance is demonstrated in the  
bandwidth and transient response. The switching  
frequency is fixed to 65 kHz. A frequency hopping  
function is also on chip, and it contributes to low EMI. In  
addition, a built-in super junction MOSFET which  
tolerates 650 V makes the design easy.
